Default to Break systems every 4 measures

I'm not sure if this is a Feature Request, or my own ignorance on how to do something, but I'm sure someone will let me know.

I write jazz combo charts and have been able to set up a Musescore Style file that I'm happy with. The one thing I haven't been able to save is defaulting the system to 4 measures per line so I don't have to manually click Format->Add/remove system breaks every time I create a new score.

If this can't be done, then consider it a Feature Request.
